TROLLEY RANGER.

Application filed December 8, 1922. Serial No. 605,577.

T0 au whom it may concem:

Be it known that I, FRANK CHESZNEKY, a citizen of Hungary, residing at Yukon, in the county of McDowell and State of V Vcst Virginia, have invented certain new and useful Improvements in Trolley Hangers, of which the following is a specification.

This invention relates to trolley wire supports or hangers, having for an object to provide a simple and efficient form of hanger which can be readily attached to and detached from the trolley wire and which Wlll securely grip the latter.

For further comprehension of the invention, and of the objects and advantages thereof, reference Will be had to the follovving description and accompanying drawings, and to the appended claims in which the Various novel features of the invention are more particularly set forth.

Fig. 1 of the drawings is a side view of one form of my trolley Wire hanger, showing a portion of a trolley wire attached thereto.

Fig. 2 is an elevation at right angles to Fig. 1.

Fig. 3 is a side elevation, partly in vertical section, showing another form of the invention.

Fig. 4 is an elevational view, partly in vertical section, at right angles to Fig. 3.

Fig. 5 is a detail perspective view of the supplementary clamping element shown in Figs. 1 and 2.

In the drawings I have indicated at 10 a trolley wire drawn to form a groove or channel 11 extending along each sicle thereof. Engaging in these grooves are lips 12 formed on the lower edges of a pair of clamping plates 13 and 14 respectively. These plates have formed integral with.their upper edges the similar semi-cylindrical pro jections 15 and 16 the fiat faces of Which register with one another, while the rounded faces are screw-threaded, the threads on the two projections registering with one another, these two members 15, 16 forming, in efect, when laid face to face a single screw-threaded stud.

As shown in the drawings the projections 15, 16 are transversely offset, with relation to their respective plates and the projection is passed through an aperture in the plate thus interlocking the two plates together.

The stud 15, 16 is threaded onto a coupling collar 17 suitably swiveled on a head 18 provided with lugs 19 whereby it is pivotally connected as at 20 to the lower and of a supporting pole 21. To cause the lips 12 to grip the wire 10 when the coupling 17 is screwed over the stud 15, 16 a pair of co-operating fulcrum ribs 15 16 are formed on the lower ends of the stud elements 15, 16.

In Figs. 3' to 5 I have shown a modified construction comprising wire gr1pping plates 18', 14: having integral parti-screw extensions 15, 16 which when laid together form a single screw. Engaged with this screw is a barre] 25 rotatably and slidably held on a spoollike member 26 having fianges 28 on opposite encls thereof, the barrel 25 having an interior recess 27 formed by enlarging its bore in which the forWard fiange 28 engages. The member 26 is provided with lugs 29 wherehy it is pivotally attached to the pole 21.

A ring 30 is placed freely over the stud 15, 16 and is provided with a pair of downwardly projecting legs 31 having V-notches 32 in their lower ends whereby they may straddle and press together the plates 13, 14: adjacent the gripping edges of the latter.

With this modified form of hanger accurate fitting of the threads on the barrel 27 and the two-part stud is not needed as the notched encls of the legs 31 force the plates 13. 14 into gripping contact with the Wire 10.

Having thus described n1y invention what I claim as new and desire to protect by Leters Patent of the United States is as fol- .ows:

1. A trolley wire support comprising a pair of vertical plates adapted to grip the sides of the wire and formed with serai-cylindrical screw-threaded upWard extensions j ointly forming a stud. said extensions being transversely offset from their respective plates, one of them extending through an aperture in the other, abutting fulcrum ribs formed on adjacent faces of said extensions. and a member screwed on said extensions and a device adapted to be pressed clownvvardly by said member to press said plates against the wire.

2. A trolley wire support comprising a pair of vertical plates adapted to grip the sides of the wire and formed with semi-oylindrical screw-threaded upward extensions j ointly forming a stud, said extensions being transversely offset from their respective plates, one of them extending through an aperture in the other, abutting fulcrum ribs formed on adjacent faces of said extensions, and a member screwed on said extensions, and a device adapted to be presScd clownwardly by said member to press said plates against the wire, said d'evice comprising a ring surrounding said extensions and having a pair of clownwardly projecting legs formed with V=notchs in their lower ends.

3. A trolley wire support comprising a pair of vertical plates 'adapted to grip the sides of the Wire and formed with semi-cylindrical screW-threaded up ward extensions jointly forming a stud, said extensions being transversely ofiset from their respective plates, one of them extending through an aperture in the other, abutting fulcium ribs 'formed on adjacent faces of said extensions,

and a member screwed on said extensions,

. atnd'adevice adapted to be pressed clownyvardly by said member to press said plates 'against the wire, said devic presenting a V-notoh in its lower end in which said plates are adapted to engage.

4. In a trolley Wire support, a pair of vertical plates adapted to grip opposite sides of the wire, andhaving semi-cylindrical upwaid extensions jointly forming a stud, a barrel screwed on said stud, and a device adapted to be pressed clownwardly by said barrel t0 Cause s'aid plates to grip the wire.

5. In a trolley wire support, a pair of vertical plates adapted to grip oppos1te sides of thewire, and having semi-cylindrical upward extensions jointly formin a stud, a barrel screwed on said stud, and a device adapted to be pressed clownwardly loy said barrel to cause said plates to grip the wire,

said device comprising a ring surrounding said stud below said barrel and having a pair of downwardly projecting legs Iormed with V-notches in their lower ends.

In testimony whereof I have afiixed my signature.

FRANK CHESZNEKY.
